Verbal Behavior is an approach to teaching language based on B.F. Skinner's analysis of language functions. Instead of teaching words as labels, VB teaches language by its purpose — manding (requesting), tacting (labeling), echoics (repeating), and intraverbals (conversational responses). A child first learns to mand (ask for things they want), which builds motivation to communicate. VB is implemented within an ABA framework and uses natural environment teaching alongside structured trials. The approach is especially effective for children who are learning to communicate for the first time, including those who use AAC devices. VB programs track each language function separately, so therapists can target specific communication gaps.
VB is delivered as part of ABA and covered under the same Medicaid benefit. Families should understand VB to evaluate whether their child's language goals are functionally meaningful.
